When jatropha seeds are crushed, the resulting jatropha oil can be processed to produce a high-quality biodiesel that can be used in a standard diesel car, while the residue (press cake) can also be processed and used as biomass feedstock to power electricity plants or used as fertilizer (it contains nitrogen, phosphorus and potassium)

Uses : Jatropha is a small tree or shrub with smooth gray bark, which exudes whitish colored, watery latex when cut. It grows between three and five meters in height, but can attain a height of up to eight or ten meters under favorable conditions.
